[Xen-devel] Branch Counters

[preetha@xxxxxxxxxxxxxxxxx]

Hello,
I would like some pointers on information about the performance counters
maintained by Xen. In the paper on ReVirt, the branch counters are used as a
means for deterministic replay. Could anyone give some hints about how to go
about doing this i.e: logging the branch counter values ?
Would appreciate any help,
With thanks
Preetha.
